<h2>Detailed Description</h2>
<p>The QIconEnginePlugin class provides an abstract base for custom <a href="qiconengine.html">QIconEngine</a> plugins.</p>
<p><b>Use <a href="qiconenginepluginv2.html">QIconEnginePluginV2</a> instead.</b></p>
<p>The icon engine plugin is a simple plugin interface that makes it easy to create custom icon engines that can be loaded dynamically into applications through <a href="qicon.html">QIcon</a>. <a href="qicon.html">QIcon</a> uses the file or resource name's suffix to determine what icon engine to use.</p>
<p>Writing a icon engine plugin is achieved by subclassing this base class, reimplementing the pure virtual functions <a href="qiconengineplugin.html#keys">keys</a>() and <a href="qiconengineplugin.html#create">create</a>(), and exporting the class with the <a href="qtplugin.html#Q_EXPORT_PLUGIN2">Q_EXPORT_PLUGIN2</a>() macro.</p>

<h2>Member Function Documentation</h2>
<h3 class="fn"><a name="QIconEnginePlugin"></a>QIconEnginePlugin::QIconEnginePlugin ( <a href="qobject.html">QObject</a> * <i>parent</i> = 0 )</h3>
<p>Constructs a icon engine plugin with the given <i>parent</i>. This is invoked automatically by the <a href="qtplugin.html#Q_EXPORT_PLUGIN2">Q_EXPORT_PLUGIN2</a>() macro.</p>
<h3 class="fn"><a name="dtor.QIconEnginePlugin"></a>QIconEnginePlugin::~QIconEnginePlugin ()</h3>
<p>Destroys the icon engine plugin.</p>
<p>You never have to call this explicitly. Qt destroys a plugin automatically when it is no longer used.</p>
<h3 class="fn"><a name="create"></a><a href="qiconengine.html">QIconEngine</a> * QIconEnginePlugin::create ( const <a href="qstring.html">QString</a> &amp; <i>filename</i> )&nbsp;&nbsp;<tt> [pure virtual]</tt></h3>
<p>Creates and returns a <a href="qiconengine.html">QIconEngine</a> object for the icon with the given <i>filename</i>.</p>
<p>See also <a href="qiconengineplugin.html#keys">keys</a>().</p>
<h3 class="fn"><a name="keys"></a><a href="qstringlist.html">QStringList</a> QIconEnginePlugin::keys () const&nbsp;&nbsp;<tt> [pure virtual]</tt></h3>
<p>Returns a list of icon engine keys that this plugin supports. The keys correspond to the suffix of the file or resource name used when the plugin was created. Keys are case insensitive.</p>
